VMM 2012 Bare Metal – Failed to Customise WinPE Image

2017-12-11T14:13:52+00:00 June 15th, 2012|Azure, Cloud|

Hi There,

I recently upgraded a customers VMM infrastructure from RC2 to RTM and had a couple of issues with the bare-metal deployments that I had previously configured.

I was able to initiate a bare-metal build, and PXE boot the machine but as it was starting to provision I had an error relating to certificates;

Error: 800b0109, A certificate chain processes, but terminated in a root certificate which is not trusted by the trust provider

First port of call was to update the WinPE image from SCVMM. However upon doing this I got the following message;


I noticed the following line in the logs when running a trace;

Check Server and WAIK installation; and files to be injected. Verify WinPE image; library and temp location. —> System.InvalidOperationException: A required privilege is not held by the client

Could UAC be an issue? I disabled it, and rebooted the server and lo and behold the update worked.

This is strange since in the RC2 installation I had UAC enabled and did this with no problems.
